ROOFING-PACKAGE AND METHOD OF MAKING seam.

Specification or Letters Patent.

Patented. March 3, 1908.

Application filed March 18, 1907; Serial No. 362,988.

To all whom it may concern:

Be it known that I, Fnnnnnrdn C. OVER- BURY, of New York, in the county of'New York and State of New York, have invented certain new and useful Improvements .111

proof material adapted to be applied in strips to roofs or side walls of buildings, such material beingt'ermed roofing, which term I will em by for convenience hereinafter. Strips of t is character are now being made 5 with one edge of each strip serrated or provided with alternating tongues and recesses, the serrated edge of each strip, when laid, being the exposed edge, and giving the root or wall a diversified appearance similar to that to produced by pointed shingles. Roofing material is ut on the market in packages, each formed by winding astrip of the material into a compact roll. I have found that, when a strip which is serrated along one edge ,is formed into a roll, one end of the roll being created by the serrations of the strip, the serrations are exposed 'and are liable to be broken oil or bent out of shape, particularly the serrations in the outer convolutions of 3c the roll.

myinvention consists in a roofin package composed of a sheet of flexible roo g mate rial, longitudinally subdivided into a plurality of roofing strips having serrated abutting edges and wound into a roll, the rojec tions of each strip alternating with an being protected by the projections of the abutting strip, the said stri s being separable when the sheet is unrolle in other words, I sever a sheet of suitable roofing material along an 4.5 irregular or zig zag line, the form of which is such as to impart serrations of the desired form to the edges created by the cut, and wind the strip into .a roll, while the subdivisions are in the same relative ositions as 2 they were before the formation oi the Zigzag out. By this procedure, the ends of the roll are formed by the straight edges of the stri s, the serrations pointing inwardly from tie ends of the roll and mutually guarding and The invention also consists in the improved method of making-a roofing package, said method consisting in longitudinally subdividing a sheet of flexible roofing material along a zig-zagline to form serrated edges and winding the subdivided sheet into a roll in which the serrated edges are abutted together.

Of the accompanying drawings, forming. a part of this specification, Figure 1 represents a side elevation showing means for ro-.

ducing my improved roofing package. ig. 2 represents a top lan view of the means shown in Fig. 1. ig. 3 represents a perspective View of a partially completed package embodying my invention, a portion of the strip forming the package being extended from the body of the package. Fig. 4 represents a top plan view showing means for subdividing the sheet along a plurality of lines to form more than two roofing strips.

The same. letters of reference indicate the same parts in all the figures.

in the drawings, a represents a sheet oi. suitable iiexible roofing material of such width that it is adapted to be longitudinally subdivided into a plurality of operative roofing strips.

In carrying out my invention, ll subdivide the sheet a into a plurality of strips (1 a, each of suitable width for a roofing strip, the sheet being subdivided by means of a zig-zag cut I) of such form as to create tongues a on each strip of In making the zig-zag out I), such instrumentalities are used as will perrnit the tongues a of each strip to remain in en agement with or between two tongues of t is abutting strip, the cut being formed without displacement of either of the subdivisions or stri s from the relative positions occupied by tire material of said strips before the cut l) was. formed. The sheet, thus subdivided, is wound into a com act roll a (about a core having flanged en s if desired) the ends of the roll being formed by the straight edges of the strips a, the serrations of the strip pointing inwardly and interlocldng, as shown in Fig. 3. A ackage is thus formed, composed of a plu-ra ity of serrated strips, the serrations of which are protect-ed against any injury or displacement while the package is in storage or transit.

in Figs. -1 and 2 l have shown suitable means for producing the above-described package and practicing the method ineenoae volved. In said 11gures, represents a top I i I claim:

roll and (Z a bed roll which supports the top roll, said rolls being mounte in bearings suitably supported. The top roll a is provided with zig-zag knives e adapted to form the longitudinal cut I) when rotary movement is imparted to the roll 0. The knives e are arranged to cut throu h the material of the sheet a their cutting e ges acting against the bed roll 0, which may be made of any material suitable for thepurpose. The cutter-carrying roll 0 may be rotated by power applied in any suitable way. The uncut s eet is preferably wound upon a mandrel g journaled in suitable bearings, the sheet bemg unwound from the roll and passed between the rolls e and d. i

'i represents a reel, upon which the roll or package a is formed by Winding up the sub divided sheet. I i

it re resents a horizontal bed or table located etween the reel and the rolls a and d, saidtable supporting the subdivided ortion of the strip between the rolls a d and t e reel, and preventing the subdivisions from separating on their way from the cutter to the ree I i In Fig. 4, I show the roll 0 provided with a plurality of zig-zag cutters e, and with an intermediate straight cutter f, the several cutters bein so arranged that the sheet a has a strai ht Iongitudinal cut g and two zig-zag cuts located between the straight cuts 9 and the margins of the sheet. thus made for cutting and winding or pack' agin four serrated strips at one operation.

I have hereinbefore referred to a zig-zag cut and zig-zag cutters. It is to be understood, however, that I -do notLmean, in using the term zig-zag ,to limit myself to cutters which form angular serrations only', it being obvious that the cutters may form-serrations or alternating projections and recesseshaving curved or scalloped edges.

Provision is 1. As an articlefof inanufacture,-.a cylin drical roofing package composed of a sheet of flexible roofing material longitudinally subdivided into a plurality of roofing strips, havin serrated abutting edges and wound into :3. r0 1, the projections of'each strip alternating with and being protected by the projections of the abutting strip,.-said strips being separable when the sheet is unrolled.

2'. As an article of manufacture, a cylindrical roofin package composed of a sheet of flexible roo ngmat'erial, subdivided by a straight longitudinal cut, and by zig-zag lon 'tudinal cuts between the straight out an the margins of the sheet, the edges formed b said cuts being abutted together,

' and the s set being wound into a roll to hold the said edges in contact with each other, the sheetbeing divisible, when unrolled, into a plurality of roofing strips each having a straight edge and a serrated edge. I

3. The method hereinbefore described of ividing a sheet of flexible roo g along a zigzag line {to form serrated edges and winding the subdivided sheet into a roll in which the serrated edges areabutted together. I

4. The method hereinbefore described of making a cylindrical roofing package, which consists in longitudinally subdividing a sheet along a plurality of lines includinga straight line and zig-zag lines between the straight line and the margins of the sheet, and winding the subdivided sheet into a roll in which all the edges formed by the lines of division are making a cylindrical roofing (package, which I consists in lon itudinally sub abutted together.
